Information Processing Device, Graphic Processor, Control Processor, and Information Processing Method

Abstract

An arithmetic processing unit in a graphics processor alternately executes a process of a first image processing which generates a main image of an application, i.e., a base image and a process of a second image processing which generates a display image eventually displayed by performing a desired processing of the base image. Processing time for the process of the first image processing is designated by a first process executing unit in a main processor which requests execution of the process of the first image processing. Processing time for the process of the second image processing is predetermined. The first process executing unit further determines an address of storage area in a frame buffer storing the base image and, upon determination, transmits to the second process executing unit which requests execution of the process of the second image processing.

Description

TECHNICAL FIELD[0001]The present invention relates to information processing technology, and more particularly to a method for information processing including image processing and an information processing apparatus, a graphics processor and a control processor to which the method is applied.BACKGROUND TECHNOLOGY[0002]Along with the recent development of computer graphics technology, image data output from an information processing apparatus such as a mainframe, a personal computer and a game console has grown more complicated and advanced. These information processing apparatuses incorporate a graphics processor specifically for image processing other than a main processor which executes common arithmetic processing, in order to offload image processing tasks from the main processor and try to eliminate overhead of the system.[0003]In these information processing apparatuses, when tasks corresponding to a plurality of applications are processed in time sharing manner, generally, a...
